(0004) * 函数库说明：LCD1602B基本驱动函数库 *
(0005) * 版本： v2.0 *
(0006) * 作者： 傻孩子 *
(0007) * 日期： 2005年9月6日 *
(0008) * 修改： 傻孩子 *
(0009) * 修改日期： 2006年1月20日 *
(0010) * *
(0011) * 说明： *
(0012) * 1、需要底层硬件驱动函数支持 *
(0013) * 基本的宏定义： *
(0014) * LCD_RS LCD_RW LCD_E *
(0015) * LCD_SetWriteData LCD_SetReadData *
(0016) * LCD_SendHalfCharHigh(a) *
(0017) * LCD_SendHalfCharLow(a) *
(0018) * 当处于串行状态下时，只定义LCD_RS *
(0019) * LCD_E LCD_LCD_SendHalfCharHigh(a) *
(0020) * LCD_SendHalfCharLow(a) *
(0021) * 2、自带基本的延时函数。需要外部提供毫秒 *
(0022) * 单向增加的两个计数器用于特效显示： *
(0023) * FlashTimeCounter RunTimeCounter *
(0024) * 3、需要修改引用宏定义来指定底层硬件驱动 *
(0025) * 函数库。 *
(0026) * 4、本库驱动下的LCD显示支持1602的各种连 *
(0027) * 接方法。当使用只写模式是请在引用该头 *
(0028) * 文件之前加上宏定义： *
(0029) * # define _Use_LCDOnlyWrite *
(0030) * 5、在调用本库之前，定义RunStringSpeed可 *
(0031) * 以设置滚屏的速度。通过在引用前定义 *
(0032) * FlashTimeOut 和 FlashGIFTimeOut 可以 *
(0033) * 改变字符闪烁的频率。 *
(0034) * 6、增加一个GIF字幕特效函数。 *
(0035) * 7、确定没有LCD复位问题。 *
(0036) * 8、增加对595串行转并行连接的支持。 *
(0037) * 需要头文件SerialToCollateral.h *
